TYPE-WRITING MACHINE.

. Specification of Letters Patent.

Application filed February 6. 1913. Serial No. 746,488.-

To oil whom it m 11?/ concern lie it known that I, OTTO PETERM'ANN, a citizen of the Republic of Switzerland, and ay resident of Groton, county of Tompkins, and State of New York, have invented certain new and useful Improvements in Typelvlriting Machines, of which the following is a full, clear, and exact description.

This invention relates more particularly to parts of the platen shift mechanism of visible or front strike typewriting machines in which the platen and carriage are adapted to be folded forward over the keyboard.

(lne of the principal objects of the invenm tion is to provide simple and etfective brackets ordevices which may be made from sheet steel or other metal in such a way that the same may be properly secured to the machine frame at thev corners thereof and which serve to guide parts of the platen shift mechanism.

Another object of the invention is to provide a typewriting machine having a twopart foldable support, each part comprising a plurality of members on one part of which the carriage is mounted, the other part being connected to the platen shift mechanism, and means whereby the members of one part of the support as well as parts mechanism may be adjusted and held in such adjusted position to permit the members of the two-part support to be properly held relatively to eachother in order that the parts may be folded freely and properly. l

A further object of the invention-is to provide means whereby parts of a foldable support may be quickly adjusted and such means made to form a part of a substantially rectangular and rigid frame in order that/the carriage may be uniformly moved and held at opposite sides of the machine when shifted to permit different characters to be printed as is usual in machines of this class.

stili further object of the invention is to prtwide brackets or guides which may be utilized as supports tor other parts of the` typewriting machine.

YWith these and other objects in view, the invention will be hereinafter more particularly described with `reference to the accompauving drawings7 which form a part of this specification. and will then be pointed 'out in the claims atthe' ,end o' the description.

In the drawings, Figure 1 is a fragmentary vertical section of a foldable typewriting machlne embodying one form of my invention. Fig. 2 is a fragmentary plan view.

with the immediate supporting means for the carriage broken away and moved to its folded position. Fig. 3 is an enlarged frag-V mentary view showing the means whereby the arms of the support and the-slides secured thereto may be adjusted. Fig. 4 is a fragmentary detail view of the ad'usting and reach rod. Fig.5 is an enlarg perspective view of one of the corner brackets or guides; and Fig. 6 is an enlarged detail perspective view of the other bracket.

While the invention is shown as applied more particularly to a machine in which the carriage and its bed may be folded forwardly over the keyboard or otherwise shifted to make the machine more compact when not in use, it will be understood that the invention may bey applied equally to a machine that does not fold or is otherwise constructed.

The frame 10 may be of a single piece of aluminum or other sheet metal and has the sides 11 and the rear connecting part or member 12. A rod 13 extends transversely of the machine between the sides 11 and to this rod is held one or more shift levers 1l. Only one shift lever 1l is employed though ordinarily in machines of this class two are used to adapt the platen to assume three different positions. The lever 14 is connected to a transverselyl extending rod 15 and this rod is rigidly held at its ends to slides or members 16. There are two slides 16 located on opposite sides of the machine and the upper ends of these slides are rigidly held to the bars or members `17 forming a part of a foldable support 18. A bar or member 19 somewhat longer than the laars 17 is arranged in parallel relation with each of the arms or bars 1T when the machine is in normal working position and at one end is pivotecL as at 20. to the arm 1T. The arms or bars 19 have a bed 21 rigidly held thereto and adapted to move along said bed is a carriage 22 in which is mounted a platen Q3. The arms with the carriage bed and carriage are adapted to be moved on the pivots "2() forwardly of the machine so that the carriage will be placed in overhanging relation to the keyboard or otherwise according to the length of the arms or mem,w

detail `at its ends is provided with threaded openings or recesses 25 and. T he, end having the opening 25 1s made so as to abut properly against the inner face of one of the arms 17 and in the same arm 17 is a counter. sunk opening through which a headed screw' '27` passes, the -end 4of which engages the threads ofthe opening 25 and holds vthe rod to said arm. The end of the rod 24 having the opening 26 is engaged by thethreaded end of a screvv '28, the said screw having its head in a countersunk opening in the other arm 17 of the support. An internally7 threaded sleevev or adjusting member 29 engages the threaded end 3() of the rod 24 and is adjustab'le lengthwise of the rod, and said sleeve may be rotated on said rod either with the fingers or by inserting a tool in one or more Iopenings 31 provided for that purpose. By this means the rod :24 may be quickly lengthened or shortened Without any special fitting of the rod and the arms 19 of the foldable support may be thus spread to adapt the vsame to be properly positioned relatively to the arms 17 in order that the said arms 19 with the carriage may fold properly.

`The end 30 of the rod 24 is slotted lengthvvise, as at to intersect the threaded portion. The purpose of this slot is to permit the diameter of the threaded end 30 of the rod to be increased in order to make a very tight fit 'with the sleeve 29 when the rod Vis/taken from the machine; Thus if occasion arises to take out some of the mechauism, and to do this it becomes necessary to remove the rod 24, the sleeve being tight on the'rod would not disturb the adjustment and in reassemliling no readjustment of the sleeve 29 would be required. I l

It willbe evident that the slides 16, rod 15 and rod 24, together with the arms 17, form a rigid and substantially rectangular frame, in order that the carriage may have a uniform vertical movement and be properly supported at both sides 'of the machine.

A bracket or guide 33 islocated at one corner of the machine frame and a bracket 34 at ythe other rear corner of the machine frame. These brackets each have a vertical portion or part v35 with side members or ivings 3G arranged at right angles. to the `verticall v arranged portion 35 andv above the Wings` and adapted to be supported' thereby is an angular horizontally disposed and overhanging'portion 36a.

The brackets may be, made of sheet steel or other metal andare firstblanked and .then bent to the shape shown thoughsaid i brackets may be made in any desired Way'.

the wings 36 of each of the brackets is also' provided with a threaded opening by which the bracket may be secured by a screw 39 to one of the sides 11 ofthe frame, thus each bracket is rigidly held in position and serves to brace and hold the members of the frame in position. The horizontal or overhanging portion 36 of the bracket 33 is provided with a round opening 40 and the overhanging portion of the bracket 34 with an elongated opening 41 for the' slides 16, other- Wise the brackets have substantially the same construction.'4 The elongated opening 41 extends transversely of the machine so that there is no .play forwardly or rearvvardly for its slide 16 but said slide is per-v mitted to have a lateral or adjusting movement transversely of the machine to `permit the rod 24 to properly position the supporting arms 19 in the manner already described. r1`he slides or members 16 are cylindrical at the upper portion thereof Where they pass through the openings of the brackets and at their ends Where they are secured to the arms 17 may be partly cut away to assist in forming a support for the arms 17 to which theyare fastened.

The bed 21 as will be seen rests partly upon the arms` 17 and thus the arms 17 and 19 when the machine is'n a normal Working. position are hcld in parallel relation so that when the slides are moved vertically the arms will both be moved together with the bed, carriage, and platen to the different shifting positions and by reason of the construction the arms 19 may be moved or shifted relatively to the arms 17 to make the machine more compact for transportation or other purposes.

The brackets 33 and 34 each have one Wing 36 provided with a threaded aperture. as 42, which is adapted to be. engaged by the threaded end of a screw 43. These screws 43 form pivots for bell-crank levers 44, and these levers may be connected to arms 45 of a universal bar, the latter being operated by the key-operated levers and the space levers in the usual way., The bellcrank levers 44 are adaptedtoA operate a rocking or movable member'vvhich-in4 turn.

serves to impart movement tothe escapement and ribbon operating mechanisms, butas such.V features form no part of the present invention,- they are Aneither illustratedy nor described.

From the foregoing, it will be manifest that Simple and efficient means is provided whereby a part of the platen shift mecha- ,nism is properly guided; that said guiding means is simple in construction and forms etlective means for bracing the frame and for guiding parts of the platen shift mechanism; and that simple means is provided whereby a two-part oldable support may have its members properly adjusted and rigidly held in such adjusted position to adapted the support to fold properly and freely.

Having thus describedmy invention, I claim as new and desire to secure by Letters Patent l. In a typevvriting machine, the combination of a support having a pair of arms, a carriage adapted to travel along said support, brackets having openings of relatively different sizes, -slides passing through the openings of the brackets and connected to the arms, means for adjusting the slides and arms in the direction of travel of the carriage, and means lfor moving said slides.
